Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, specifically a screening device for feed production. Background Technology

[0002] Feed is a type of food used to raise animals in animal husbandry. It is made from a mixture of soybeans, soybean meal, corn, grains, etc. In the process of feed production, it is often necessary to screen the feed raw materials. Feed production raw material screening device is a device used to screen feed raw materials.

[0003] Existing technologies, such as the utility model patent with publication number CN213001145U, disclose a raw material screening device for pig feed production and processing. This device includes a base plate, a first screening box mounted on one side of the top of the base plate, a first screen mounted inside the first screening box, a first vibrating motor mounted on one side of the bottom of the first screening box, a first discharge port on one side of the first screening box, and a second screening box located below the first discharge port. The second screening box is mounted on one side of the top of the base plate, a second screen mounted inside the second screening box, a second vibrating motor mounted on one side of the bottom of the second screening box, and a second discharge port on one side of the second screening box. By changing the structure of the raw material screening device, secondary screening of pig feed raw materials is achieved, thereby separating out small particles that can be directly used, avoiding further processing of directly usable small particles and residue, reducing processing time and lowering processing costs.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: In the process of screening feed raw materials using a raw material screening device for feed production, it is often difficult to remove dust or small impurities from the raw materials. This causes the dust to fly up when the device vibrates, resulting in it re-adhering to the surface of the raw materials and polluting the surrounding environment. Therefore, there is a need for a screening device for feed production. Utility Model Content

[0005] The purpose of this utility model is to provide a screening device for feed production, which blows dust into the collection chamber through the installed bellows and diverting nozzles, and sprays atomized water mist through the atomizing nozzles to complete the dust treatment, thereby solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a screening device for feed production, comprising a base plate, a screening frame installed on one side of the upper surface of the base plate, a slot provided in the middle of the screening frame, a filter frame snapped into the slot, a filter screen glued into the filter frame, and a collection bin slidably inserted into the slot below the filter frame.

[0007] A filter plate is movably installed inside the collection chamber, and an atomizing nozzle is installed through the rear side of the collection chamber.

[0008] A bellows is installed on the upper part of the screening frame corresponding to the position of the filter screen.

[0009] Preferably, the slot has two sets of slots inside, a through hole is opened through the rear side of the slot, two sets of baffles are symmetrically installed on both sides of the upper surface of the screening frame, and two sets of vibration motors are bolted to the rear side of the slot.

[0010] Preferably, the filter frame is snapped into the slot at a 60° angle, and a set of elastic retaining plates are installed at both ends of the filter frame. The elastic retaining plates are elastically snapped into the slots, and two sets of slots are symmetrically opened on the lower surface of the filter frame.

[0011] Preferably, the upper surface of the base plate is symmetrically provided with two sets of sliding grooves inside the slot, and four sets of rotating wheels are symmetrically installed in pairs at the bottom of the collection chamber, with the rotating wheels rotatably installed inside the sliding grooves.

[0012] Preferably, a set of limiting plates is installed at each of the four corner points on the lower side of the collection chamber, the filter plate is placed against the upper surface of the limiting plates, and two sets of insert plates are symmetrically installed at the top of the collection chamber, with the insert plate slide grooves inserted into the two sets of grooves.

[0013] Preferably, the atomizing nozzle has a set of hoses sealed at its inlet end, and the hoses extend from the inside and are sealed to the external water pump.

[0014] Preferably, a mounting bracket is snapped onto the top of the baffle plate, and a diversion nozzle is installed through the center of the mounting bracket. The air box is bolted to the top of the diversion nozzle for continuous installation.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The inclined design of the screening frame allows all feed to roll freely during the filtration process. The vibrating motor accelerates the screening of feed materials through the filter screen. Simultaneously, the installed bellows and diversion nozzles blow air to one side of the filter screen, guiding dust into the collection chamber for targeted processing of fine debris or dust. Atomizing nozzles installed inside the collection chamber spray the dust, causing it to fall quickly to the bottom. The filter plates inside the collection chamber can separate foreign objects, achieving better separation and processing of impurities. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides: a screening device for feed production, such as... Figures 1-7 As shown, the device includes a base plate 1, a screening frame 3 is installed on one side of the upper surface of the base plate 1, a slot 4 is opened in the middle of the screening frame 3, a filter frame 9 is snapped into the slot 4, a filter screen 10 is glued into the filter frame 9, a collection chamber 12 is slidably inserted into the slot 4 below the filter frame 9, a filter plate 15 is movably installed inside the collection chamber 12, and an atomizing nozzle 17 is installed through the rear side of the collection chamber 12; a bellows 20 is installed on the upper part of the screening frame 3 corresponding to the position of the filter screen 10.

[0027] Preferably, the slot 4 has two sets of slots 5 inside, and a through hole 6 is opened through the rear side of the slot 4. Two sets of baffles 7 are symmetrically installed on both sides of the upper surface of the screening frame 3. Two sets of vibration motors 8 are bolted to the rear side of the slot 4. The slots 5 inside the slot 4 cooperate with the elastic plate 11 to limit the filter frame 9, so that the feed raw materials can slide smoothly through the filter screen 10. The dust and impurities inside the feed raw materials can be shaken down into the collection chamber 12 by the operation of the vibration motor 8. The through hole 6 on the rear side of the slot 4 allows the hose to extend and connect to the external water pump to ensure the temperature of the atomizing nozzle 17 inside the collection chamber 12. The baffle 7 installed at the top of the screening frame 3 can limit the mounting frame 18, so that the air delivered by the diversion nozzle 19 is aligned with the filter screen 10 to complete the dust guiding work.

[0028] Furthermore, the filter frame 9 is snapped into the slot 4 at a 60° angle, and a set of elastic clamping plates 11 are installed at both ends of the filter frame 9. The elastic clamping plates 11 are elastically snapped into the slot 5. Two sets of slots are symmetrically opened on the lower surface of the filter frame 9. The filter frame 9 is installed at a certain angle so that the feed raw materials can roll down smoothly. The filter frame 9 can be quickly removed through the elastic clamping plates 11, so that different mesh sizes of filter screens 10 can be quickly replaced according to production needs. At the same time, the filter screens 10 can also be quickly cleaned.

[0029] Furthermore, two sets of sliding grooves 2 are symmetrically opened on the upper surface of the base plate 1 inside the slot 4, and four sets of rotating wheels 13 are symmetrically installed on the bottom of the collection chamber 12. The rotating wheels 13 are rotatably installed inside the sliding grooves 2. The sliding grooves 2 opened on the upper surface of the base plate 1 cooperate with the rotating wheels 13 at the bottom of the collection chamber 12, so that the collection chamber 12 can be pulled out more flexibly to complete the cleaning of the inside of the collection chamber 12.

[0030] It is worth noting that a set of limiting plates 14 are installed at the four corners on the lower side of the collection chamber 12. The filter plate 15 is placed against the upper surface of the limiting plate 14. Two sets of insert plates 16 are symmetrically installed at the top of the collection chamber 12. The insert plates 16 slide into the two sets of slots. The limiting plates 14 installed inside the collection chamber 12 limit the filter plate 15, so that the filter plate 15 can separate foreign objects and dust, making the later cleaning of the device more convenient. The insert plates 16 installed at the top of the collection chamber 12 are inserted into the slots, so that the collection chamber 12 is more tightly connected to the filter frame 9, preventing the escape of dust and foreign objects.

[0031] Specifically, a set of flexible hoses is sealed at the end of the atomizing nozzle 17. The hoses extend from the inside and are sealed to the external water pump. The hoses can ensure that the collection chamber 12 can bend freely during movement, avoiding connection problems between the atomizing nozzle 17 and the water pump after the collection chamber 12 is pulled out and reset.

[0032] In addition, a mounting bracket 18 is snapped onto the top of the baffle plate 7, and a diversion nozzle 19 is installed through the center of the mounting bracket 18. The air box 20 is bolted to the top of the diversion nozzle 19 and connected to it. The mounting bracket 18 limits the diversion nozzle 19. When the air box 20 is working, the diversion nozzle 19 disperses the airflow, so that the airflow does not concentrate in one place and cause dust to be blown away, thus completing the guidance of the airflow. Since the mounting bracket 18 is snapped onto the upper part of the baffle plate 7, the mounting bracket 18 can be removed first when disassembling the filter frame 9, reducing the impact on the removal of the filter frame 9.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
